我不明白为什么，但是当我的console.log() -- box和box.color --都告诉我它没有定义……我尝试了许多不同的方法来解决这个问题，但都失败了。

下面是script.js：

var app = angular.module('LoginApp', ["firebase", "ngRoute", "ngCookies"])


app.provider("box", function ()
{
    var hex = "SomeColor";
    var UID = 3;
    return {
        setColor: function (value)
        {
            UID = value
        },
        $get: function ()
        {
            return {
                color: hex
            }
        }
    }
})

app.config(function ($routeProvider, $cookiesProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'HtmlFiles/registration.html',
        controller: 'regController'
      })
     .when('/logIn', {
        templateUrl: 'HtmlFiles/login.html',
        controller: 'loginController'
      })

      .when('/Chat', {
        templateUrl: 'HtmlFiles/Chat.html',
        controller: 'chatController'

      })
      .when('/Test' , {
        template: '<h3>This is just a testing phase</h3>',
        controller: 'Testing'
      })

      .when('/userSettings', {
        templateUrl: 'HtmlFiles/userSettings.html',
        controller: 'userSettingsController'

      })

      .when('/room', {
        templateUrl: 'HtmlFiles/room.html',
        controller: 'roomController'
      })

      .otherwise({
        redirectTo: '/'
      }); 
});

app.controller('Testing', ["$scope","roomService", "roomProvider",  function($scope, roomService, roomProvider){
  console.log("This is from the Controller Service: " + roomService.room.roomUID)
  console.log("This is from the Controller Provider: " + roomProvider.$get)
  }
])
app.factory("Auth", ["$firebaseAuth",
  function($firebaseAuth) {
    var ref = new Firebase("https://chattappp.firebaseio.com/");
    return $firebaseAuth(ref);
  }
]);

app.factory("Ref", function(){
   var ref = new Firebase("https://chattappp.firebaseio.com/")
   return ref;
})

app.factory("UniPosts" , function(){
  var ref = new Firebase("https://postss.firebaseio.com/")
   return ref;
});

app.service('getCookieService', ["$cookieStore", "$scope", 
          function($cookieStore, $scope){
            this.getCookie = function(name){
              $cookieStore.get(name)
            }
          }
    ])

roomController.js：

app.controller('roomController', ["$scope", "Auth", "Ref", "AuthService", "roomService","$http",
    function($scope, Auth, Ref, AuthService, roomService, $http,box) {
    // Sweet Alert :)
     function generateRandomStringToken(length) {
            var string = "";
            var characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
            for (var i = 0; i < length; i++){
                string += characters.charAt(Math.floor(Math.random() * characters.length));
            }
            return string;
        }

        swal({
            title: "Room",
            text: "What do you want your room name to be?",
            type: "input",
            showCancelButton: true,
            closeOnConfirm: false,
            animation: "slide-from-top",
            inputPlaceholder: "Write something"
        }, function(inputValue) {
            if (inputValue === false) return false;
            if (inputValue === "") {
                swal.showInputError("You need to write something!");
                return false
            }
            swal("Nice!", "You wrote: " + inputValue, "success");
             $scope.$apply(function () {
            $scope.roomNameModel = inputValue
            });

           console.log($scope.roomNameModel)
    var redirectPage = generateRandomStringToken(10)
     console.log("User gets redirected to : " + redirectPage + " ...")
     roomService.setRoomUID(redirectPage);
     console.log(roomService.room.roomUID)
     console.log(box) //Undefined...
     console.log("From Provider : " + box.color)//box.color is undefined..


        });




    }
])
    //window.location.hash = "/Test"

好的，现在它起作用了，但我对如何在app.config上使用它感到困惑。我的提供者是Hash：

app.provider("Hash", function ()
    {
        var UID = 0;
        return {
            $get: function ()
            {
                return {
                    setHash: function (value)
                    {
                        UID = value;
                    },
                    getHash: function()
                    {
                        return UID;
                    }
                }
            }
        }
    })

当它到达控制器时，我设置哈希并得到哈希.roomControler.js：

app.controller('roomController', ["$scope", "Auth", "Ref", "AuthService", "roomService","$http", "Hash",
        function($scope, Auth, Ref, AuthService, roomService, $http,Hash) {
    // Sweet Alert :)
     function generateRandomStringToken(length) {
            var string = "";
            var characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
            for (var i = 0; i < length; i++){
                string += characters.charAt(Math.floor(Math.random() * characters.length));
            }
            return string;
        }

        swal({
            title: "Room",
            text: "What do you want your room name to be?",
            type: "input",
            showCancelButton: true,
            closeOnConfirm: false,
            animation: "slide-from-top",
            inputPlaceholder: "Write something"
        }, function(inputValue) {
            if (inputValue === false) return false;
            if (inputValue === "") {
                swal.showInputError("You need to write something!");
                return false
            }
            swal("Nice!", "You wrote: " + inputValue, "success");
             $scope.$apply(function () {
            $scope.roomNameModel = inputValue
            });

           console.log($scope.roomNameModel)
    var redirectPage = generateRandomStringToken(10)
     console.log("User gets redirected to : " + redirectPage + " ...")
     roomService.setRoomUID(redirectPage);
     console.log(roomService.room.roomUID);
     Hash.setHash(redirectPage);
     console.log("From Provider : " + Hash.getHash())
    window.location.hash = "/Test"
        });




    }
])

现在，我想要做的是在我的app.config()中说，当它在Hash.getHash()中时，转到模板:和控制器：

所以像这样的..。

    app.config(function ($routeProvider, $cookiesProvider, Hash) {
        $routeProvider.
         when('/' + Hash.getHash(), {
               template: '<h4> Your in Room',
               controller: 'Test
                })
});

app.controller('Testing', ["$scope","roomService","Hash",function($scope, roomService, Hash){
  console.log("This is from the Controller Service: " + roomService.room.roomUID)
  console.log(Hash.getHash())//This Logs right. :D
  }
])

前面我想说的是，我想在app.config() when语句中以某种方式配置随机生成的Hash。所以在我的app.config里。当用户在/RANDOMLYGENERATEDHASH中时，有一个模板：'<h1>Test</h1>'。这是我试过的，但剂量有效.

它是.when()语句上的第四个语句。

app.config(function ($routeProvider, $cookiesProvider, HashProvider){
    $routeProvider
      .when('/', {
        templateUrl: 'HtmlFiles/registration.html',
        controller: 'regController'
      })
     .when('/logIn', {
        templateUrl: 'HtmlFiles/login.html',
        controller: 'loginController'
      })

      .when('/Chat', {
        templateUrl: 'HtmlFiles/Chat.html',
        controller: 'chatController'

      })
      .when('/' + HashProvider , {
        templete: '<h1>Test</h1>'
      })
      .when('/userSettings', {
        templateUrl: 'HtmlFiles/userSettings.html',
        controller: 'userSettingsController'
      })
      .when('/room', {
        templateUrl: 'HtmlFiles/room.html',
        controller: 'roomController'
      })

      .otherwise({
        redirectTo: '/'
      }); 
});

现在是供应商..。

app.provider("Hash", function ()
{
    var UID = 0;
    var _getHash = function()
    {
        return UID;
    };
    return {
        getHash: _getHash,
        $get: function ()
        {
            return {
                setHash: function (value)
                {
                    UID = value;
                },
                getHash: _getHash
            }
        }
    }
})

这是我的roomcontroller.js现在..：(控制器底部的重要细节)

app.controller('roomController', ["$scope", "Auth", "Ref", "AuthService", "roomService","$http", "Hash","$routeParams",
        function($scope, Auth, Ref, AuthService, roomService, $http,Hash, $routeParams) {
    // Sweet Alert :)
     function generateRandomStringToken(length) {
            var string = "";
            var characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
            for (var i = 0; i < length; i++){
                string += characters.charAt(Math.floor(Math.random() * characters.length));
            }
            return string;
        }

        swal({
            title: "Room",
            text: "What do you want your room name to be?",
            type: "input",
            showCancelButton: true,
            closeOnConfirm: false,
            animation: "slide-from-top",
            inputPlaceholder: "Write something"
        }, function(inputValue) {
            if (inputValue === false) return false;
            if (inputValue === "") {
                swal.showInputError("You need to write something!");
                return false
            }
            swal("Nice!", "You wrote: " + inputValue, "success");
             $scope.$apply(function () {
            $scope.roomNameModel = inputValue
            });

           console.log($scope.roomNameModel)
    var redirectPage = generateRandomStringToken(10)
     console.log("User gets redirected to : " + redirectPage + " ...")
     roomService.setRoomUID(redirectPage);
     console.log(roomService.room.roomUID);
     Hash.setHash(redirectPage);
     console.log("From Provider : " + Hash.getHash())
     $routeParams.hash = Hash.getHash()

        });




    }

还有script.js(注:这并不是我仅有的一个。您可以在Cloud9上看到上面链接上的所有其他链接(Plunk未更新)：

            return {
                setHash: function (value)
                {
                    UID = value;
                },
                getHash: _getHash
            }

    }
})

app.config(function ($routeProvider, $cookiesProvider, HashProvider){
    $routeProvider

      .when('/Chat', {

      })
    .when('/:Hash', {

      .when('/userSettings', {

代码中有两个问题：

"roomController“的定义 App.controller(“房间控制器”，["$scope"，"Auth"，"Ref"，"AuthService"，"roomService"，"$http"，函数($scope，Auth，Ref，AuthService，roomService，$http，box) ){}

只要匹配参数和它们的声明，您就会发现忽略了"box“参数的声明。正确的"roomController“定义应该如下所示：

app.controller('roomController', ["$scope", "Auth", "Ref", "AuthService", "roomService","$http", "box",
        function($scope, Auth, Ref, AuthService, roomService, $http,box)

“盒子”提供商。您将"setColor“方法定义为提供程序的配置方法，但您正在尝试将其用作提供程序结果方法。修正后的版本应如下： app.provider("box"，函数() { var十六进制= "SomeColor"；var UID = 3；返回{ $get:函数() {返回{颜色:十六进制，setColor:函数(值){ UID = value })

角度提供者

对EDIT2的回答：

您定义了HashProvider。要在app.config中配置它，您应该将参数作为HashProvider传递(不仅仅是Hash，而且当您尝试在除app.config之外的任何地方使用它时，您应该将其作为Hash注入)。因此，您的app.config声明应该如下所示：

app.config(function ($routeProvider, $cookiesProvider, HashProvider)

为了让您访问...and方法，有必要将其移动到提供者配置，例如：

app.provider("Hash", function ()
{
    var UID = 0;
    var _getHash = function()
    {
        return UID;
    };
    return {
        getHash: _getHash,
        $get: function ()
        {
            return {
                setHash: function (value)
                {
                    UID = value;
                },
                getHash: _getHash
            }
        }
    }
})

对EDIT3的回答：

现在我明白了你想做的事。问题是你试图做错了:)。正确的方法更简单。您必须使用param进行配置路由，例如：

.when('/:hash', {
    template: '<h1>TEST TEST</h1>',
    controller: 'any controller'
})

把它放在你最后一条路线的后面。之后，在控制器中，您可以使用$routeParams对象访问哈希。例如：

$routeParams.hash

然后，在控制器中，您可以分析它是否正确并执行必要的操作，或者在散列无效时将用户重定向到某个地方。
